If he's still around (he'd still be alive for sure, but I don't know if he might have retired or not) then Brian Pope (I think that's the right surname, it's been a while) down at 'link automotive' -(also known as mini-link and mini link automotive) - is a gun with webers. Naturally he's got most experience with mini a-series engines, but an a-series datto won't exactly be a 'new experience' for him afaik! They were down in Thornton Crescent Mitcham, and I think the number was 9873 3874 - if that doesn't work, google them :)
